PATENT iol-*Fica f TULSA, OKLAHOMA, A CORPORATION OF OKLAHOMA BULL WHEEL applicati@r ined Maren 19, 1928. serial No. 262,848.

My invention relates to bull wheels of the type employed in connection with oil well drilling equipment, and has for its principal object to provide a wheel of that character wherein the belt and brake members may be easily and quickly assembled on orremoved from their shaft without interference with the wheel structures, and wherein the wheel members are automatically adjusted to proper angular relation with the shaft upon application to the shaft.

It is a further object of the invention to provide a wheel of that character whereinV air resistance, disturbing air currents and noiseincidental to operation of wheels of this character are reduced to a'minimum.

In accomplishing these and other objects of the invention I have provided improved details of structure, the preferred forms of which are illustrated in the accompanying drawings, Vwherein Fig. 1 is a perspective view of a set of bull wheels in assembled relation on a shaft.

Fig. 2 is a section on the line 2-2, Fig. 4, the shaft being broken away to illustrate the mounting of the wheel hubs thereon.

Fig. 3 is a section on the line 3-3, Fig. 2.

Fig. 4 is a section on the line 4-4, Fig. 2.

Fig. 5 is a detail perspective view of a pair of mated hub members. Y Y

Fig. 6 is a sectional view of a modified form of hub.

Referring in detail to the drawings:

1 designates a bull wheel shaft of ordinary7 tubular construction, having the usual gudgeons 2 fixed in its outer ends and adapted for rotatable mounting in suitable bearings (not shown).

Y Mounted on the respective ends of the shaft are belt and brake wheels 3, 4, embodyingf the novel structural features constituting my invention.

The belt wheel 3 includes a hub unit 5 consisting of mated collar members 6 and 7, web disks 8 attached to the hub collar 6 and carrving a tug rim 9, having the usual rope` grooves 10 the disks and rim 9 being preferablyconstructed of sheet metal, having lips 11 and flanges 12 connected by rivets 13 to form a unitary structure.

The web disks 8 arepreferably dished out-V L wardly to afford greaterV rigidity and are provided with central openings 14 for receiving the rim 15 of the outer hub collar which is provided with peripheral flanges 16 slightlyV inset from its ends to form shouldered rings 17 for seating the disks; the` disks being secured to the anges 16by rivets 18.

Formed integrally with the rim 15 of the collar member 6 is an inner bearing member 19 provided with inner and outer tapered, annular seats 20 and 21 terminating at their adjacent'ends in circumferential bearing walls 22 and 23, separated by a radial wall 24 (Fig. 5).

'Formed integrally with the collar member 6 and extending inwardly from; the radial wallor shoulder 24 are tapered keeper bosses 25'e`qually spaced inftheir circularrelation and with relation to the circumferential wall portion23.

Openings 26 positioned midway "between the bosses 25 and extending through the shoulder 24 and through bosses27 on` the outerside ofthe collarare adapted to receiving bolts orA the like for connecting the respective members of the hub unit.

The inner hub collar 7 comprises conical portions `28and 29 adapted for engagement in the seats 20 and 21 respectively ofthe collar member 6, circumferential wall portions 30 and 31 at the adiacent ends of the conical portions adapted Afor location within the mating wall portions 22 and 23 in the collar 6, and a radial wall. or shoulder 32v separating the circumferential walls 30 and 31 and provided with rectangular openings 33 extending laterallv through the'wall 32 and adapted for receiving the keeper bosses 25 of the collar member 6.

Apertures 34 located midway between the lopenings 33 and terminating in squared sockets 35 in bosses 36 onthe inner side of the wall 32 are adapted Vfor receiving bolts 37 which extend through the mating openings 26 inthe member 6 to attach thehub members together when'in assembledrelation; the squared heads ofthe bolts seating in the sockets 35 andthe onposite ends of the vbolts being .provided with nuts 38 which engage braking surface; the segments being arranged in overlapping relation and connected by rivets 43 or like fastening' means extended through the lips of the disks and through the segments. Y

In assemblingf the apparatus, the inner col-V lars 7 ofthe hub units 5 are fixed to the shaft in properI spaced relation to form an integral shaft unit Which retains its identity as such throughout the period of its practical usefulness.

The Wheels 3 and 4. which 'are primarily composed of the outer collars 6 ofthe hub units 5 and the Web disks 8 with assembled rims 9 and 4l respectively. also constitute complete units which may be assembled with or removed from the hub portions 7 that are fixed on the shaft l by removing the bolts 37 whereby the Wheels are retained in assembled rela-tion on the shaft.

Being so constructed, the Wheels may be readily dismonnted from the shaft for shipment or transfer to different Well locations, Without disturbing their individual unit oonstruction,V therefore 'obviatinfz possiblitv of misalignment when thev are again assembled ,Y

on the shaft for operation, and resulting in 'considerable saving,r of time due to the simplicity of the assembling operation.

In the modified form shown in Fig. 6 the inner hub comprises separable hub members 44'and 45 having tapered surfaces 46 adapted for mating with, tapered surfaces 47 Within an outer hub member 48. bolts 49 be ing` applied through the members for retainbearing portions` .means in the abutment' flanges for keying the members in assembled relation. and means for retainingr the members in keyed relation.

2. In vcombination vwith shaft and Wheel members, a sleeve fixed to the shaft member and having outwardly facing cone element thereon. a sleeve fiXed to'the Wheel member and having a. cone element for receiving the element on the shaft, said cone elements having concentric lateral bearing portionsx and radial abutment flanges intermediate said bearing portions, means in the abutment fianges for keying the members in assembled relation, including projecting lugs in one flange and complementar)7 sockets in the matingflange, adapted to receive the lugs, and means for retaining the members in keyed relation.

In combination With'shaft and wheel members, a sleeve fixed to the shaft member having conical endv portions of unequal diameters, each conical portion continuing in a lateral bearing portion terminating at the approximate center of the sleeve, a radial stop Wall .connecting the ends of said bearing portions, a sleeve fixed to the Wheel member and having conical end portions, bearing portions and a slop wall complementary to said port-ions of the shaft sleeve member, means in the abutment flanges for keying the members in assembled relation and means for retaining the members in keyed relation.

In testimony whereof I aix my signature.
